cannot be settled in the present account, as I mean here to 
conclude it ; but will add in the Journal, observations of as 
late a date as possible. 
The mean right ascensions of the stars here given, were de- 
duced from observations made in the meridian with a small 
transit instrument, and are, I believe, accurate. The declina- 
tions are not settled with greater precision than to two or three 
minutes ; and although quite sufficient to prevent any mistake, 
I have, for the satisfaction of those who wish to make further 
observations on them, drawn up the annexed plan, in which all 
the stars they were compared to, can easily be found; no greater 
exactness is intended. (See Tab. II.)

The other Variable that I have discovered is, as already men- 
tioned, in the Northern Crown. Its right ascension and de- 
clination have just been given, as likewise the plan of the stars 
near it. This star, although not in Flamstead's catalogue, is 
marked on Bayer's maps of the 6th magnitude. Several 
years ago, in 1783, 1784, and 1785, I suspected it to be 
changeable, which induced me to make the memorandums 
here copied in the Journal, since which time I have often seen 
it, but not perceiving any alteration, the dates were neglected 
until the spring of 1 795 ; I then had the satisfaction of finding 
my suspicions confirmed, it being invisible; but on the 20th of 
June, it appeared of the 9.10th magnitude, and went through 
mdccxcvii. T
